Reading Force sensing resistors values via ADC of nrf52DK

Hi,

I need to make two FSRS to read and display the output simultaneously. So, initially I had to get the ADC values from two analog pins at the same time. After struggling a bit, I was able to get it. Now, I need to get the force readings from FSRS. The vDD was taken as 5V since I connnected both the FSRs to the same 5V pin in the nrf52 dk. R_DIV was taken as 2500 ohms. However, the readings I obtained were not accurate. This is because, the ADC values show values fluctuating between 0,1,-1,2. It’s very confusing for me.

Can anyone help me with this?

Thanks!
